The BF202 On-Line Blown Film Gauge

Retrofit Existing Blown Film Lines with Precise Profile Monitoring and Average Thickness Control

The BF202 Blown Film Gauging System retrofits easily to existing blown film lines, and it measures blown film with market leading precision. The BF202 is a two headed version of the BF200 gauging system. These two heads provide data at twice the speed of a single head, and this can also be useful if there is not a full 360 degree rotation/oscillation of the die or haul off. The system consistently holds calibration to deliver an accurate measurement even on the thinnest films and is designed to be easy to use and durable in harsh and dirty environments. Along with monitoring the shape of the bubble, and it has the unique ability among capacitance gauges to provide average thickness control . The BF202 is a much more economical alternative to on-the-bubble gauging systems due to it’s lower capital and installation cost.

On-Target Blown Film

The blown film process has many variables that affect film thickness. This complexity puts a large burden on the operator as he tries to achieve on-target thickness. SolveTech’s breakthrough technology has opened the door to significant improvements in your production. The BF200 Blown Film Gauging System is an affordable tool that combines reliable thickness readings with simple, trouble-free performance.

Enhance Existing Equipment

Adding a BF200 Blown Film Gauging System to an existing extruder is a good way to get the most out of your equipment. It will help you generate significant savings in time and material. Catch upsets or drifts that may occur and get operator feedback that enables quicker set-ups. This proves to be a cost-effective way to improve quality and reduce scrap.

Durable in Tough Environments

In 2009, SolveTech found the mean time between failures to be 120,000 hours based on a sample of 5 million operating hours on blown film lines. The system is designed to handle tough environments, and it is designed to negate any dirt, changes in temperature or changes in humidity. It is also simple to operate and maintain, basically requiring little to no regular maintenance. SolveTech systems are designed to last and have run in the field for over 25 years.

Provides a Stable and Accurate Measurement

The picture below shows a graph of the unit with a stationary film sample inside the gauge head. As shown below, the measurement stays stable over 4 hours of operation in this example.

Requirements for Successful Implementation

The technology can only measure non-conductive materials, and it cannot measure metals or foils.

The unit measures one spot along the edge, so the line has to have a rotating/oscillating die or an oscillating haul-off to generate a complete profile. The unit tracks the rotation and generates a profile as the film rotates through the gauge.
